RE: nitro fuels
There are no magic fuels.
However, there is a magic oil that is used in glowfuel. It's castor oil. It is great insurance. However, it also has a weakness. Too much of it isn't good in the long run. So look for a fuel that has a castor/synthetic blend of oils. Beyond that..... ain't no magic fuels, and for the most part, ain't no bad ones.
